Hi Alan, I have noticed it ;). Right now I am less than optimistic that I will be able to find the cause: - I have tried to reduce the differences between wish (failing) and plserver (working) to a minimum (by loading the Pltk package dynamically, by excluding manner of extra bits and pieces, such as the renaming of [exit]): no change in behaviour.
- I have identified that the call to plP_escape to initialise the xwin device is instrumental to the crash and I thought that perhaps the display connection was closed twice, leading to the problem. So, I have made sure that it occurs only once (passing on the connection from Tcl/Tk to the xwin device instead of opening a new one and allowing Tcl/Tk to close it via the [exit] command). Still no positive result. - I have studied the source code, but I have not found any location where the difference in behaviour might be coming from. One possibility is that the Tcl/Tk library is built with threads enabled and the crash occurs in some pthreads routine. Whether that is any clue (and how to take advantage of that knowledge) is unclear to me. Well, so far my detailed feedback. Regards, Arjen > -----Original Message----- > From: Alan W.
